EXPLANATION.
Two zeroes are = √2 and -√2
zeroes of polynomial.
=> x = √2 and x = -√2
=> x - √2 and x + √2
products of zeroes of polynomial.
=> ( x - √2 ) ( x + √2 )
=> x² - 2
divide 3x³ - 4x - x² + 2 by x² - 2
we get,
=> 2x - 1
Now,
zeroes of the equation
=> 2x - 1 = 0
=> x = 1/2
Therefore,
All zeroes are = 1/2 , √2 , -√2
